Answer is A, because the total is 6 dollars, so all we're trying look for is how many nickels and quarters are there to give us 6 bucks in total. 36-n is basically the amount of total coins minus the number of either nickels or quarters found
Answer: Three plus Five equals Eight or 3= a · 5= 5a
Step-by-step explanation:
Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
We have,
Question 1. i.e. i.e. x = ±9.
Question 2. i.e. i.e. i.e.
Question 3. [tex]f(x)=x^{2}-144[tex]
For the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
So, the options are 12 and -12.
Question 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
So, Antoine is incorrect. There exists two solutions x=5 and x= -5.
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x = 1 ±
Answer:
D. 75x+160<760
Step-by-step explanation:
The reason is 75 has to be a variable because it changes with time. The fee is a fixed rate that will not change no matter the time. All of these values must be less than 760 meaning the variable and constant must be less than (<) 760
